Abstract

The invention provides a motor control method, a motor control circuit and a food processor. The motor control method comprises the steps of detecting the zero-crossing point of AC voltage of an AC power supply, outputting a trigger pulse after a delay time starting when the zero-crossing pint of the AC voltage is detected, and triggering a switching device connected with the motor to be conducted. At least two trigger pulses outputted after different delay times are different in pulse width.

Description

technical field [0001] The present application relates to the field of small household appliances, in particular to a motor control method, a motor control circuit and a cooking machine. Background technique [0002] With the improvement of people's living standards, many different types of cooking machines have appeared on the market. The functions of the cooking machine mainly include, but are not limited to, functions such as making soybean milk, squeezing juice, making rice noodles, mincing meat, shaving ice, making coffee, and / or preparing facial masks. There is a situation that the switch device connected to the motor of the existing cooking machine cannot be triggered. Contents of the invention [0003] The application provides a motor control method, a motor control circuit and a cooking machine, which can avoid the situation that the switching device cannot be triggered. [0004] One aspect of the present application provides a motor control method. The motor c...
